Simulation instability. Couldn't read results, so nothing was sent back. [I checked my work folder and there's no results file for 08.]

Thanks for the report, anko1

If past experience is any guide, XTC errors seem to be associated with a full disk or some other similar condition (like interference from an AV program) preventing FAH from reading and writing whatever it wants in it's work directly.

Thanks for the input, Bruce. It's been awhile since the error, so I may not recall correctly, but I think there were some errors on the following units, and when I checked the work folder there were a lot of stray files hanging around (files left from other units), so that may have been it. I cleaned it up and things have been going well since.
